Delivering effective and safe lung cancer stereotactic body radiation therapy (SBRT) requires technology that can account for lung tumor motion. Both fiducial-based and markerless tracking algorithms currently exist, with markerless being a focus of innovation, investment and research in the field. These tracking algorithms, however, have not been benchmarked using a common, prospective measurement methodology. The American Association of Physicists in Medicine (AAPM) designed the MArkerless Lung Target Tracking CHallenge (MATCH), an AAPM Grand Challenge, to compare the precision and accuracy of existing markerless tracking algorithms.
Accuray customers, using the Accuray Synchrony® Lung Tracking™ with Respiratory Modeling on the Radixact® System, the next-generation TomoTherapy® platform, and CyberKnife® System, achieved the highest levels of accuracy and precision, taking top honors in the AAPM MATCH challenge.
